FLUORESCENT LIGHTING GENERAL INFOFluorescent aquarium lights come with T12 lamps (1.5" diameter), T8 lamps (1" diameter) or T5 lamps (5/8" diameter).
Compact fluorescents are also, as the name implies, a type of fluorescent light--but we put them all in their own
compact fluorescent lighting section. Many of our
metal halide lights also come with fluorescent lamps--usually actinics.
T5 Lamp Aquarium Lighting
T5 aquarium lights have become extremely popular in the past couple years. When run with an electronic ballast, which all of our T5 HO lights use, T5s are said to be more energy efficient, longer lasting and cooler running than other types of aquarium lights. Because the lamps are thin, they will penetrate the water better than thicker compact fluorescent and other fluorescent types of bulbs. T5s are a great choice for tanks that are 20 inches and deeper.
All of our fluorescent aquarium lights come with T5 bulbs (though we do sell T12 and T8 replacement lamps). The T5 bulbs are either normal output (NO) or high output (HO).
Normal output T5 fluorescents are low wattage and should only be used for fish only tanks. We carry the following normal output lights:
